Case (2): A 57 year old male patient with history of rectal adeno-carcinoma with hepatic metastasis. a) Baseline axial T2 MRI revealed mostly hyper intense lesion in segment VIII/V interface. b) Corresponding axial baseline diffusion weighted image of the previous T2 target lesion with b value of (800 m2/sec) shows the lesion displaying hyper intense signal. c) pre therapeutic ADC image which revealed diffusion restriction and ADC value of 0.73 x10-3 m2/sec. (d) post therapeutic (21 days after chemotherapy) ADC map showing increase in the ADC value up to 0.96 x10-3 m2/sec (e) base line pre chemotherapy CT portal phase; hypo dense lesion with relative peripheral enhancement was noted measuring about 5.6 cm. (f) 2 month follow up CT portal phase revealed significant reduction of the lesion currently seen measuring about 2.3cm (partial response according to RECIST criteria)
